Elon Musk's social network X has introduced the feature of making audio and video calls directly from the app to its Android client. The feature will be available to Android users after an app update. Any user can receive a call, but only paid users can place a call. X has also published its vision for 2024, including launching peer-to-peer payment and new xAI-powered features. However, reports suggest that advertisers are leaving X after Musk's controversial statement at an event in November 2023.
